CHURN.

ASi?E@IFICATIE@N forming part of Letters Patent No. 340,154, dated April 20, 1886.

Application filed January 4, 1886. Serial No. 187,569. (No model.)

To all whom it may concern/.f

Be it known that I, ANDREW J. RAMsEY, a citizen of the United States, residing at Liberty Centre, in the county of lVells and State of Indiana, have invented a new and useful Improvement in Ghurns, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvementsin churns; and the novelty consists of the peculiar construction, combination, and arrangement of parts, substantially as hereinafter fullyset forth, and specifically pointed out in the claim.r

My invention has for its object to provide means whereby a violent agitation is created among the particles of the cream to churn the same very quickly and by means which shall be very simple, strong, durable, and light in construction.'

A further object of .my invention is to provide rotary dashers which revolve simultaneously in opposite planes with driving-gearing and supporting devices that can be readily applied to churn-vessels of varying-sizes, and to provide means for throwing either one of the dashers out of operation.

In the accompanying drawings, Figure 1 is a perspective view of a churn embodying my invention, the cream-receptacle being omitted for the sake of clearness. Fig. 2 is a vertical sectional view on the line x of Fig. 3, and Fig. 3 is a similar sectional View taken at right angles to the plane'of section of Fig. 2 on the line y y of that figure.

Referring to the drawings, in which like letters of reference denote corresponding parts in the several figures, A designates the lid of of a churn, vessel, or receptacle, both of which are of the common or any preferred construction; B, the gearing-supporting frame; C, the operating or driving shaft, and D E the dasher-staffs, independently geared to the drivingshaft and driven thereby to rotate in opposite planes.

The supporting-frame B comprises two upright vertical standards, B', that are located on opposite side edges of the cover A, and secured thereto by means of screws, Src., which pass through perforated lugs or feet b of the standards, and a horizontal frame, B2, that is bolted to the standards by studs or bolts that pass throughthe frame and the standar and receive securing-nuts. The horizont frame is provided with a transverse or cros bar, b3, that is arranged at or near its midd and connects the side bars of the frame, wi which it is cast or formed integral, said ce tral crossbar having an enlarged portion boss that provides a bearing for the upper er of the dasher-staff E.

The driving-shaft C is journaled and su ported in boxes c in the upper ends of tl standards B', said shaft having bevel or mit gear-wheels C C2, keyed thereon` or fastene by feathers c', and one end of the shaft is e: tended beyond one of the bearings c, and pri vided with a crank-handle, c2, for its conve] ient rotation by hand.

The dasher-staff D is made hollow and t1 bular, and the dasher-staff E i-s arranged then in, independently thereof, to rotate in opposil directions, the tubular dasher-staff havin blades d at its lower end and at right angle thereto and a miter or bevel gear-wheel D z its upper end. The upper end of this tubula dasher-staff Dis extended through the loopt cover A of the churn, and the bevel gea] wheel D is keyed thereon and meshes Wit the gear-wheel G/ of the drivingshaft C, Washer, d, or other bearing` being interpose between the gear-wheel D and the cover A .to prevent friction and Wear between th parts.

The dashershaft E extends through am projects above and below the tubular shaft D and at its lower end the shaft E is provider with radial dasher-blades e, while its uppe end has a bevel gear-wheel, E', keyed thereon The upper end of the dasher-staff E extend: through the bearing b4 of the central cross-bal of the horizontal frame B2, and it receives i transverse pin, e', that bears on said cross-bai of the frame, to suspend the dasher E there from, and the gear-wheel E is keyed or fixer' on its shaft above the gear-wheel D', so as t( be out of contact or engagement therewith.

This being the construction of my improvec churn, the operation thereof is as follows The dashers are 'inserted in the churn-vesse and the supporting-frames proper adj usted or and secured to the top or cover thereof. The

crankhandle of the driving-shaft is rotated by hand or otherwise, and the bevel gearwheels C C2 thereof transmit the rotatory motionV to the gear-wheels D E of the dashers, which rotate in opposite directions, so that their blades create a violent agitation of the cream in the vessel.

Either of the gear-wheels C Cz can be ad justed laterally on the drivingshaft by remov' ing or loosening their fastening-keys or feathers so as to throw either one of the dashers out of operation; and by removing the key e and the gear-wheel E the dasherlstaff E can be removed from the frame and churn for the purpose of cleansing the same.

The core A is fastened to the churn-vessel by means of hooks and eyes or other equivalent fastenings.

The various gearwheels are of different sizes, but they are so proportioned that they rotate the staffs at the same rates of speed and in reverse or opposite directions.

I am aware that it is not new to provide a churn with a cover having vertical standards in which are journaled a driviug-shaft that carries bevel gear-wheels of different diameters, one of said wheels meshing with a similar Wheel on a vertical tubular dasher-shaft that is supported in the cover and the other wheel with a similar wheel of a solid dasherstallc that extends through the tubular stall.

I am also aware that it is not new to provide a churn-cover with two parallel "vertical standards connected by a horizontal cross-bar, in which are journaled the upper ends of two 35 parallel independent dasher-staifs that carry bevel-pinions at their upper ends which bear on the horizontal cross-bar and mesh with bevel gear-wheels on a driving-shaft journaled in the upper ends of the vertical stand- 4o ards.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a churn, the combination, with the churn- 45 top A, the vertical standards B', secured thereto, a horizontal frame, B, secured to the standards by bolts b2, and having a central crossbar, a driving-shaft, C, journaled in bearings in the standards and having bevel gear-wheels 5o C C, keyed thereon, a tubular dasher-staif, D, having blades d and a gear-wheel, D', keyed thereon, and a dasher-staif, E, journaled in the cross-bar of the horizontal frame by a pin and provided with blades and a gear-wheel, 55 E', keyed thereon, substantially as described.

In testimony that I claim the foregoing as my own I have hereto athxed my signature in presence of two witnesses.

ANDREW J. RAMSEY.
